Introducing PARCi

June 12, 2018

Mapping data is a powerful way to share information. Maps simplify complex patterns and make otherwise complicated information accessible to a broad audience. Maps join information about the world with a locational component and thus yield deeper insights that can help explain the way things are and how they came to be that way. Such visual mapping of data is increasingly necessary for any research project.

However, building maps for research projects can be difficult and time consuming. First you have to find the source data you want to use for your map and too often this data is locked behind expensive paywalls. If you need historical data, it can be tricky to find the data at all. Then you need to clean the source data by removing any unnecessary information from the file and converting the file into a format that you can work with. Once you’ve sourced, cleaned, and converted your data, then you still need to find a platform on which to create the map, analyze the data, and visualize your findings. Any of these steps might require technical skills beyond your capacity and all of these steps take time away from the real task at hand: analyzing and visualizing information. Often, you end up spending more time finding data and setting up the maps than doing the analysis itself.

PARCi simplifies this process by offering 200+ years of demographic data mapped and visualized for you. Just select a year, zoom into the desired scale, and click to view detailed demographic data fully rendered in charts and diagrams. Data is visualized at the nation, state, county, city, census tract, and census block scales. PARCi allows you to skip over the laborious data prep and map building process and instead go straight to viewing data and analyzing visualizations. With PARCi, you can quickly discover social and demographic trends, reveal hidden patterns, and compare changes over time.

So far, we’ve focused PARCi on visualizing census data and we will continue to add census data to PARCi until we have the entire historical and contemporary census covered. Additionally, in the coming weeks and months, we will be extending our database of city-level data in PARCi to include historical street grids, plat lines, and building information. Our goal is to make PARCi the most comprehensive resource for spatial data.

As part of our commitment to open data access, we’ve made PARCi 100% free. You can have unlimited access to view all maps and charts in the PARCi database, absolutely free of charge. Support our mission to make spatial data easily accessible and freely available to all by signing up today.
